Sometimes you need to use more domains for your blog.
Like, www.superwbd3.tk & superwbd3.tk.
If you set one, even if you point your DNS to its ip address, it won't make any difference.
Just add these to your blog's wp-config.php:
$wphome = 'http://'.$_SERVER['HTTP_HOST']; $wpsiteurl = 'http://'.$_SERVER['HTTP_HOST']; define('WP_HOME', $wphome); define('WP_SITEURL', $wpsiteurl);
That 's it.
